This book is a sign of its times. Each one of the chapters - papers
written by European authors of various backgrounds- illustrates a
departure from the style of theorizing that has been prominent in
the behavioral and social sciences for most of the century. Until
very recently, models for behavioral phenomena were chi~fly based
on numerical representations of the objects of concern, e. g. the
subjects and the stimuli under study. This was due in large part to
the influence of nineteenth century physics, which played the role
of the successful older sister, the one that had to be imitated if
one wished to be taken seriously in scientific circles. The
mystical belief that there could be science only when the objects
of concern were susceptible of measurement in the sense of physics
was a credo that could not be violated without risks. Another, more
honor able justification was that the numerical models were the
only ones capable of feasible calculations. (In fact, these models
were typically linear. ) An early example of such theorizing in
psychology is factor analysis, which attempted to represent the
results of mental tests in a real vector space of small dimen
sionality, each subject being represented by a point in that space.
A dimension WaGBP interpreted as a scale measuring some mental
ability. The analysis was simple, and only required an electrical
desk calculator (with spinning wheels), and a suitable amount of
determination.
